titleOfInvention | Seed powder supply pipe, method for transferring seed powder, and method for producing olefin polymer |
abstract | An object of the present invention is to provide a method for efficiently producing an olefin polymer by suppressing sheeting in a gas-phase fluidized-bed polymerization, and an equipment and an operating method therefor. Kind Code: A1 A pipe used for transferring a seed powder to a gas-phase fluidized-bed polymerization reactor for olefins with a carrier gas, wherein the inner surface of the pipe is a seed powder supply pipe made of a fluororesin. A method of transferring seed powder, wherein the seed powder is transferred to a gas-phase fluidized-bed polymerization reactor for olefins by a carrier gas using a pipe made of a fluororesin. 1. A method for producing an olefin polymer, comprising a step of transferring a seed powder to a gas-phase fluidized-bed polymerization reactor for olefins by a carrier gas using a pipe whose inner surface is made of a fluororesin.
